International intellectual property law encompasses patent, copyright, and trademark regulations that are shaped by various global treaties and agreements, primarily facilitated by the World Intellectual Property Organization (WIPO). It addresses emerging issues in IP, such as the protection of domain names and traditional knowledge, while offering streamlined processes for international patent and trademark applications through systems like the Patent Cooperation Treaty (PCT) and the Madrid System. Copyright law is supported by international treaties, while trade secret protection and enforcement standards are governed by national laws and the TRIPS agreement.
